ABSORBER OF ABSORPTION TYPE REFRIGERATOR

PROBLEM TO BE SOLVED: To provide an inexpensive absorber of an absorption type refrigerator by a rational improvement while avoiding an unnecessary increase in size.SOLUTION: An absorber 5 is constituted by disposing a plurality of absorber modules 21 in a horizontal direction and in a vertical direction in an absorber body 20 integrated with an evaporator 7. The absorber module 21 is constituted by disposing 6 stages of trays 23 in the same specification, in a vertical direction at a predetermined pitch, below an absorption liquid spray means 22. The absorption liquid spray means 22 is constituted by forming absorption liquid spray holes dispersed in a horizontal direction in a bottom face of a liquid reservoir tray for reserving the absorption liquid to a predetermined liquid depth. Each liquid reservoir tray and a lower part of the absorber 5 are connected to each other by a fourth pipe line 28 in which an absorption liquid pump 26 and a supercooling device 27 are set, supercooling of the absorption liquid is performed while circulating, and an amount of a refrigerant to be absorbed by the absorption liquid is increased. A flow volume regulating valve 29 is set at a connecting part of the fourth pipe line 28 to each liquid reservoir tray 24 to supply the absorption liquid in a constant amount to each liquid reservoir tray 24.
